我想用JavaScript解压一个GZIP字符串

const zlib = require('zlib');

// GZIP字符串
const gzipString = 'H4sIAAAAAAAACrW0TUvDQBCG7/0KAAAA//8=';

// 解压GZIP字符串
const buffer = Buffer.from(gzipString, 'base64');
zlib.gunzip(buffer, (error, result) => {
  if (error) {
    console.error('解压失败:', error);
    return;
  }
  const uncompressedString = result.toString();
  console.log('解压后的字符串:', uncompressedString);
});
